Abstract
This invention relates to an improved process for producing morpholine and its derivates by reacting ammonia and dialkylene glycol. The improvement resides in continuously charging the dialkylene glycol and ammonia to a trickle bed reactor, operating the reactor under conditions such that the dialkylene glycol is maintained as a discontinuous liquid phase and the morpholine formed is predominantly in the vapor phase.
